The invention relates to means for use in connection with a coal car to facilitate the loading,r and unloading ol lumber, the device being ot' such torination as to admit of its ready attachment to or disengagement 4from the side ot' a coal car or like carrier.

'lhe drawing illustrates a preferred cnihodinient ot' the invention. llon'ever, it iS to be tuu'lerstood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details ot' construction may be resorted to without departing t'rom the nature of the invention as claimed hereinafter.

.ln the drawing hereto attached,

Figure 1 is a view in elevation of a lumber loadingr and unloading device embodying the invention showing the same in posh tion on the side ot' a car or other carrier, a portion ot the side of the car being shown only.

Fig. 2 is a sectional detail on the line 2 2 of Fig. 1.

Fig. 3 is a sectional detail on the line 3-3 of Fig. 1.

Corresponding and like parts are referred to in th'e following description and indicated in the several views of the drawing by like reference characters.

The device comprises a hanger which consists ot'- companion hooks 1 and a connecting plate 2, the latter being ianged at its ends and secured in any manner to corresponding members ot' the hooks 1. The hooks are adapted to engage over the upper edge of the side 3 ot a coal car or other carrier. To prevent slipping ot the hanger the .tree ends of the hooks l are toothed or serrated, as indicated at 4. The plate 2. is formed with a boss 5 which is internall threaded to receive a screw 6 which is pointed at its inner end to make positive engagement vwith a. side of the support 3 and thereby positively hold the device in the required posi- A keeper 7 is secured to the )late 2 and is outwardly dellected intermediate of its edge portions lo forni a socket to receive f' standard H.

H is tubular. as indicated most clearly inA Fig. 3 and its upper end is constructed to receive the pivot fastening l0. Washers 13 are mounted upon the fastening 10 between the upper end ot' the standard 8 and the cross piere t) and support the cross piece at such an elevation as to enable it to clear the hanger when turning to adapt itself to the movement of the lumber being lloaded or unloaded. The standard 8 is adjustable in the hanger and is secured in the required adjusted position by means of a pin 14 which is adapted to pass through'an opening in the socket and through one of the series ot' open-ings 15 formed in the standard. A short chain lt connects the pin 14 with the. hanger to prevent loss or misplacelnent of the pin.

In practice the device is applied to a side ot.l a coal car or other carrier by passing the hooks 1 over the upper edge of the side attcr which the screw (l is turned to cause its inner end to engage or bite into the side 8. The standard is adjusted to the required position and made secure by the screWG in the manner stated. The lumber to be loaded or unloaded is supported upon the roller 1'2 and is adapted to be tilted and moved thereon, said roller adapting itself so as to enable the lumber to be readily moved and handled.

The foregoing description and the drawing have reference to what may be considered the preferred, or approved form of my invention. may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Having thus fully described my invention, what lf claim as new and desire t0 secure by Letters Patent isz- A lumber loading and unloading device, comprising a hanger consisting of hooks und a plate having itsv opposite ends [hinged und sex-uref] tu the hooks, said plete bein'g provided with am internally threw-led buss, n keeper secured ut its ends to the lute und havin its middle portion deflecte to form a vertically disposed socket, a screw mount'.- ed in the boss, u standard adjustable in said vertical socket, a cross piece at the upper -end of the standard mounted to turn about :l verlivn] axis, und :L llm'izmitali relier mu'- l'ied by the vross piece.
